towing 2007 Corolla

I am going to be towing my 07 corolla with a Uhaul car trailer and they told me that my car will sit low and that I have to raise the ramps. Has anyone ever towed a Corolla with a Uhaul trailer? if so how much will I have to raise the ramps? thanks for your time

Once you set the ramps down, Set a 2x4 under the end of them. Use the tongue jack to jack up the front of the trailer to make it a straight shot up on the ramps. it isnt rocket science.
